1. When the TV is connected to the computer, the TV does not display.

You have to set it up on the computer, but it will not be displayed after the connection. Also, are you connecting via HDMI, VGA or S-Video? The TV also needs to be set up (input selection)

According to what you added, you did it correctly, but you did not press the FN key until you entered the system. The FN key is invalid before entering the system.

If it still doesn’t appear after you press the FN key, then you need to right-click on the desktop and select a display setting. Because I don’t know whether your specific system is XP or WIN7, and I don’t know which kind of graphics card you have, so this setting may be slightly different. But in short, it is the display settings, such as copying, extending or independent. You have to choose one of them.

2. Why can’t the computer watch TV?

There are two ways to watch broadcast TV on the computer. The first is to use a TV card, usually with a PCI interface. Plug it into the white PCI slot on the motherboard, then turn it on, use the included installation disk to install the driver, and usually also install the software for watching TV (the installation disk comes with it) ), then plug in the cable TV signal cable, then plug in the sound output cable (included) to the sound card, start the TV watching program, and you can use your computer to watch TV. Advantages of the TV card: No need to connect to another power supply, it draws power directly from the motherboard and installs it in the chassis, taking up no space. You can record TV programs and save them on the hard drive. Generally, there is a scheduled recording function, so you don't have to worry about missing the TV programs you want to watch. The image is stable. If the refresh rate of the screen is 85Hz, it will also be 85Hz when watching TV, which has little impact on the eyes. Disadvantages of the TV card: It needs to occupy a slot on the motherboard, occupies an extra interrupt, increases the burden on the system, and can easily cause instability, especially conflicts with the camera. When watching TV, the computer must be turned on and the chassis must be working, which wastes resources and shortens the life of the hardware. General household TV card: 150-300 yuan. Second, it uses a TV box, which is external and comes with a power supply. It is easy to install. You only need to plug the TV signal cable into the input end of the box, connect the output end to the monitor, and then connect the power supply. Turn on the power and monitor and watch TV. Advantages of the TV box: Easy to connect, completely separated from the chassis, only the monitor is required. It is easy to use and can be used easily by people who do not know how to use computers and software. Disadvantages of the TV box: The TV box cannot record TV programs because it does not pass through the chassis. Broadcast television uses a refresh rate of 50Hz, and our monitors far exceed that. But even so, when watching TV, the refresh rate of the TV format will still be 50Hz, which is harmful to the eyes for a long time. Generally, a TV box costs 300-400 yuan. In addition, you can download Internet TV software and watch TV through the Internet, but the effect is completely incomparable with real hardware reception! Generally, the picture is poor and the definition is not high. The most important thing is that you have to go online to watch TV. There is also a kind of online TV, similar to BT. The more people watching at the same time, the faster the speed. However, you lose the freedom of choice. If you encounter a relatively unpopular channel, it is almost impossible to watch it.

3. Why can’t the computer play movies and TV shows?

Two solutions for the driver (first check the small speaker or check in the control panel to see if mute is set, and then check whether there is sound output through headphones. If so, it is caused by a faulty speaker or speaker. If so, it is the sound card. The driver is damaged.

1. There are many reasons why the computer cannot connect to the TV.

2. There is only one step to check, desktop machine, if your TV is high-definition and your graphics card is DVI/OUT, then you only need to consider one connection method, DVI-TV (1, see if the TV has a DVI input port, 2, there will definitely be an HDMI input port),

3. If the TV has a DVI input port, buy a DVI-DVI cable and connect it to the TV.

4. If not, buy a DVI-HDMI cable and pay attention to which one you should buy* ** Or female header. Only this method is digital transmission, which has the best effect. The others are analog signals, which deviate from high definition.

5. The difference between DVI and HDMI is that HDMI can transmit audio, while ordinary graphics cards do not have integrated sound cards. Also you need to buy an audio extension cable. The prices of the cables I bought are as follows: DVI-HDMI 10-meter cable, 160, audio extension 10 meters, 20.

6. After connecting, turn on the TV first, then turn on the computer. After entering the system, right-click the mouse on the desktop and select the "Properties" menu in the pop-up menu.

"Copy" allows the picture to be displayed on two output devices at the same time. "Vertical span" means to divide the picture into vertical sides and display them from two output devices respectively.

9. Because we mainly want the picture to be displayed on the TV, so select the "Copy" option here. Then select your favorite display device as the main display in the "Display" drop-down box below.

10. The signals on the monitor and TV are the same, so others can no longer use the computer while watching the movie. Is there any way to use the computer and watch the movie without delay? The answer is yes. Just enter the settings of the display card again and see that one of the options on the left is "Full Screen Video". This option cannot be seen when the TV is not connected.

7. What to do if the computer cannot connect to the TV

1. Choose a video interface that both the computer graphics card and the TV have, such as VGA, S-Video, and HDMI, and go to the computer store to buy the corresponding connecting cable. If your desktop computer is connected using VGA, you will also need to buy a VGA one-to-two adapter and a male-to-female adapter to connect the TV and computer monitor at the same time, otherwise the resolution cannot be adjusted. In addition to the HDMI digital interface that does not require audio cables, other analog interfaces also require their own dedicated audio cables.

2.

8. What should I do if the TV display is incomplete after the computer is connected to the TV?

When we use an HDMI high-definition cable to connect the computer and the TV, if the aspect ratio of the computer and the TV is inconsistent, for example, the computer monitor is 16:9, while the TV is 16:10. In this case, the TV screen will not be full and black borders will appear around it. At this time, we need to adjust the properties of the graphics card and use the scaling function of the graphics card to achieve our best display effect.

1. Intel graphics card (usually integrated graphics card)

Open the control panel of the intel graphics card. In the general settings, there is the scaling option, select the custom aspect ratio, adjust the scaling, and To achieve the best effect we want, see the picture below:

2. ATI graphics card settings Open the control panel of the ATI graphics card, find the "Preferences" button in the upper right corner and click the left mouse button, and select the drop-down menu Click "Advanced View" in the menu, click "Properties (Built-in Display)" under "My Built-in Display" on the left menu, and select scaling options such as "Full Screen" on the right according to actual needs (the default setting is to maintain aspect ratio ), click the "Apply (A)" button to complete the setting after confirming it is correct. See the picture below: Note: If the scaling option is gray and cannot be set, you need to adjust the resolution to a non-optimal resolution before setting it. After the setting is completed, modify the resolution to the best mode. The modification will not affect the scaling option. . If you need to modify it again, you can adjust the resolution again and then modify it.

3. Nvidia graphics card Nvidia Open the Nvidia graphics card control panel, select "Adjust desktop size and position" under the "Display" column, use the graphics card scaling function, compare the TV display, and adjust to the best display we need The effect is enough. See the picture below. Note: If some options of the graphics card are not available, or there are other circumstances, it is recommended to upgrade the graphics card driver to the latest version, so that you can better utilize the graphics card functions and adjust the best display conditions we need.
